Medical Weight Management

2016 – 2018

Medical weight management includes patient education in shared monthly nutrition visits and medical supervision in shared monthly medical appointments. Each group of participants focuses on 1 of 3 diet regimens: meal replacement, Mediterranean diet, or protein-sparing modified fast.

Meal Replacement Mediterranean PSMF
N = 144 268 179
Average months in program 13.7 18.0 15.5
Ended program 64 141 97
Switched to other diet 21 18 24

PSFM = protein-sparing modified fast.

Medical Weight Management Program Weight Loss

N = 532

In the past three years, 73% of patients active in the program for at least 3 months lost at least some of their body weight. Forty-five percent (N = 237) lost at least 5% of their starting body weight. Mean entry weight was 254 pounds. Current program duration averages 18.0 months.

Medical Weight Management HbA1c Change by Program Type

N= 113

MR = meal replacement

PSMF = protein sparing modified fast.

HbA1c = glycated hemoglobin A1c, a glycated hemoglobin fraction.

All three dietary programs showed a mild improvement in HbA1c for prediabetic and diabetic patients. The upper limit of normal for HbA1c is 5.6%.

There is some overlap in population for each diet, as participants may switch between them. Each set of bars represents the change in A1c only for the duration of that participation.
